我想测试
Android 6的权限,但我找不到使用Espresso点击“允许”按钮的方法.有没有办法做到这一点？
Espresso的版本是2.2.1.
考试：
@Test
public void acceptFirstPermission() throws Exception {
onView(withText("ALLOW")).perform(click());
}
行为：
I still receiving the frozen screen with the Dialog (like on the screenshot). Test executing all time until he becomes finished.
输出：

解决方法
我看到你正试图测试应用程序权限.我认为用Espresso测试它可能是不可能的.您可能需要将此操作作为另一个名为uiatomator的UI测试工具.
uiatomator是Google制作的另一款出色工具,可让您测试Android系统功能,如通知和屏幕锁定.您可以将它与Espresso测试框架一起使用.
